FURNACE WALL Application filed December v10 abl held in the vertical relation inthe outer One of the objects of my invention is to construct a wall of interlockable high'refractory, unit, individually expansible, blocks, 1 inside of an outer wall, holding the inner wall inverticalalignment with the outer wall while the inner wall may freely expand-horizontally and vertically.

Another object of my invention is to con-- 20 struct a composite furnace or-generator wall consisting of an outer wall of masonry and an inner wall or lining of high refractory materials that will automatically adjust itself to the unequal expansion of the two walls and 5:5 parts thereof, due to their. differences of temperature and simultaneously circulate air be tween the two walls in proximity to the inner surface of the inner wall to maintain'that difference of temperature and with the furthur object in' view.of utilizing the heat units for other'purposes. 1

A still further object of my invention is to construct a fixed outer wall of masonry, a horizontally slidable, vertically-movable in- 85 I terlockable inner wall of high refractory materials and maintain a uniform air space exposing the maximum area of the inner surace of the said inner wall to. a 'circulatable body of air therein.

I accomplish this by utilizing the interlockable unit expansion block referredto in my co-pending application for improvements in air cooled furnace expansion blocks. 45 The salient features of my invention herevinafter described, pointed out and claimed are illustrated in the accompanying draw- ,ings, wherein similar numerals refer to like part throughout the several views, in 59 which-:'-' y 19, 1925.

Figure 17 is an isometric View of one of the segmental spacer or filler brick, slidably interlo pkable with the bricks illustrated in Fig ure The block 1, shown in Figures 1 and 2, illustrating one form of the interlocking means integral with the inner wall and interlocking by means of the groove 2, tongue 3, notch 18, and boss 19, is substantially rectangular in shape having two bulged portions'circular in shape, one on each side. of the block, which bulged portion interlocks with the cooperating block shown in Figures 3 and 4.

The block 5 in Figures 3 and 4 which is one of a pair is integral with the outer wall and when built up therein, the end containing the bulged portion and the bulged portion interlocks therein as illustrated in Figure 11.

This block 5 has a shoulder 6 fitting against the end 7 of block 1, and a cup shaped opening 8 into which fits the bulged portion 4 of block 1.

The blocks 5 are set in spaced relation in the outer wall 9 so that the block 1 can freely move Vertically in the space 10.

The block 13 shown in Figure 5 is of similar construction as is shown in Figures 1 and 2 except that the V-shaped portion 11 is substituted for the bulged portion 4.

The complementary blocks 12 one of which is shown in Figure 6 has a V-shaped groove or part 14, cooperating with the V 11 in block 13 and as hereinbefore stated the block 13 may move vertically in the space 10.

Blocks 1 and 13 upon the completion of a wall built up with a series of superimposed, broken jointed, air cooled expansion blocks 16, have their faces 15 flush with the inside face of the blocks 16 and in perfect alignment therewith, as clearly illustrated in Figures 11 and 12.

It will be noted that in Figure 15 the filler blocks 17 shown in Figure 16 interlock in between the blocks 1, (see Figure 12) in slidable engagement therewith at 20 and that the spaces 22 between the blocks 17 and bricks 1 will allow freely for any horizontal expanl of similar construction as is the block 13 exsion of the wall, while the space 10 compensates for the vertical expansion of the inner wall as a whole.

The bosses 23 on the outer face .of the blocks 16, form a uniform air space 24 between the inner face 21, of the spacer block tal blocks in a wall which consists in a pair of blocks, one of which is shown in Figures 9 and 10, that project beyond the inner face 9 of the outer wall 25 into the air passage or space 24, and hold the bonding blocks either 1 or 13 in furnaces or 28 in generators as clearly shown in Figures 13 and 14.

The blocks 31 project beyond the inner face 9 of the outer wall 25, arranged in pairs in spaced relation to each other, interlockable with a block or brick similar to 13 or 1 and are provided with curved surfaces 32 as clearly shown in Figures 9, 10 and 13.

Having thus described and illustrated thepreferred embodiment of my invention I do not desire to limit myself to the exact construcion shown except so far as the same may bespecifically claimed, since it is evident that modifications may be made without departing from the spirit of the invention or scope of the claim.

ll claim A tie block fora double wall construction, shouldered on two opposite faces for inter? locking sliding engagement'with one wall tween said two opposite faces, engagement means for securing it to the other wall structure constructed to provide clearance for movement in a direction at rlght angles to th sliding movement.
